Description

Die Erfindung betrifft eine strömungstechnische Installation mit einem an einem Strömungskanal zu montierenden Antrieb, der dazu ausgebildet ist, über eine Welle, die in einer Wand des Strömungskanals gelagert ist, ein im Inneren des Strömungskanals angeordnetes Stellorgan anzutreiben, und mit einem Verdrehsicherungselement, das dazu ausgebildet ist, an der Wand des Strömungskanals gehalten zu werden und seinerseits den Antrieb in Position zu halten.The invention relates to a fluidic installation with a drive to be mounted on a flow channel, which is designed to drive an actuator arranged in the interior of the flow channel via a shaft which is mounted in a wall of the flow channel, and with an anti-rotation element which is designed for this purpose is to be held on the wall of the flow channel and in turn to hold the drive in position.

Strömungstechnische Installationen dieser Art sind aus US 8 038 075 B1 und US 5 096 156 A bekannt.Fluidic installations of this type are out US 8 038 075 B1 and US 5,096,156 A known.

Bei dem Stellorgan kann es sich beispielsweise um eine Klappe eines Volumenstromreglers handeln, mit dem der Volumenstrom in dem Strömungskanal geregelt wird. Um die Klappe zwischen einer geöffneten Stellung und einer stärker geschlossenen Stellung zu verschwenken, wird dann mit Hilfe des Antriebs, der beispielsweise einen Elektromotor aufweist, ein Drehmoment auf die Welle ausgeübt. Durch das Verdrehsicherungselement wird dabei verhindert, dass sich das Gehäuse des Antriebs aufgrund des Reaktionsmoments um die Achse der Welle dreht.The actuator can, for example, be a flap of a volume flow controller with which the volume flow in the flow channel is regulated. In order to pivot the flap between an open position and a more closed position, a torque is then exerted on the shaft with the aid of the drive, which has, for example, an electric motor. The anti-rotation element prevents the housing of the drive from rotating about the axis of the shaft due to the reaction torque.

Aufgabe der Erfindung ist es, eine Installation zu schaffen, bei der sich das Verdrehsicherungselement einfach an unterschiedliche Montagesituationen anpassen lässt.The object of the invention is to provide an installation in which the anti-rotation element can be easily adapted to different mounting situations.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Verdrehsicherungselement eine einstückige Platte mit mindestens einer vorgeschwächten Biegelinie aufweist, an der zwei Teile der Platte in ihrer Winkelstellung gegeneinander verstellbar sind.This object is achieved in that the anti-rotation element has a one-piece plate with at least one pre-weakened bending line, on which two parts of the plate are mutually adjustable in their angular position.

Dadurch, dass die Platte an der Biegelinie mehr oder weniger stark gebogen wird, lässt sich die Konfiguration der Platte an die unterschiedlichen Montagesituationen anpassen, beispielsweise an unterschiedliche Positionen des Antriebs relativ zu der Wand des Strömungskanals und/oder an Strömungskanäle mit unterschiedlich geformten Wänden.Because the plate is bent to a greater or lesser extent on the bending line, the configuration of the plate can be adapted to the different mounting situations, for example to different positions of the drive relative to the wall of the flow channel and / or to flow channels with differently shaped walls.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.Advantageous refinements are specified in the subclaims.

In einer Ausführungsform weist die Platte zwei parallele und vorgeschwächte Biegelinien auf, die die Platte in einen an der Wand des Strömungskanals gehaltenen Abschnitt, einen mit einem Antriebsgehäuse verbundenen Abschnitt und einen dazwischen liegenden Verbindungsabschnitt gliedern. Durch Biegen der Platte an den beiden Biegelinien lässt sich die Steilheit des Verbindungsabschnitts und damit der Abstand zwischen dem Antriebsgehäuse und der Wand des Strömungskanals variieren.In one embodiment, the plate has two parallel and pre-weakened bending lines, which divide the plate into a section held on the wall of the flow channel, a section connected to a drive housing and a connecting section located therebetween. By bending the plate at the two bending lines, the steepness of the connecting section and thus the distance between the drive housing and the wall of the flow channel can be varied.

Der Teil der Platte, der an der Wand des Strömungskanals gehalten ist, kann einen Basisteil und mindestens eine Lasche aufweisen, die über eine ebenfalls vorgeschwächte Biegelinie mit dem Basisteil verbunden ist, so dass sich durch Biegen der Platte an dieser Biegelinie das Verdrehsicherungselement an unterschiedliche Querschnittsformen des Strömungskanals anpassen lässt, beispielsweise an kreisförmige Querschnitte mit unterschiedlichen Durchmessern.The part of the plate which is held on the wall of the flow channel can have a base part and at least one tab which is connected to the base part via a likewise weakened bending line, so that by bending the plate on this bending line, the anti-rotation element has different cross-sectional shapes of the flow channel can be adapted, for example to circular cross sections with different diameters.

Im folgenden wird ein Ausführungsbeispiel anhand der Zeichnung näher erläutert.An exemplary embodiment is explained in more detail below with reference to the drawing.

Die in Fig. 1 gezeigte Installation ist an einem Strömungskanal 10 angeordnet, der im gezeigten Beispiel einen kreisförmigen Querschnitt hat, und weist eine Klappe (Stellorgan) 12 auf, die auf einer quer durch das Innere des Strömungskanals verlaufenden Welle 14 gehalten ist und sich mittels eines Antriebs 16 so verschwenken lässt, dass sie den Strömungsquerschnitt in dem Strömungskanal 10 mehr oder weniger verengt.In the Fig. 1 The installation shown is arranged on a flow channel 10, which in the example shown has a circular cross section, and has a flap (actuator) 12 which is held on a shaft 14 which runs transversely through the interior of the flow channel and thus pivot by means of a drive 16 leaves that it narrows the flow cross-section in the flow channel 10 more or less.

Von dem Antrieb 16 ist hier nur ein quaderförmiges Antriebsgehäuse 18 gezeigt, das außerhalb des Strömungskanals 10 angeordnet ist. Die Welle durchsetzt eine Öffnung in der Umfangswand des Strömungskanals 10 und verbindet so den Antrieb 16 mit der Klappe 12. Der Antrieb 16 kann beispielsweise einen elektronisch gesteuerten Elektromotor aufweisen, mit dem ein Drehmoment auf die Welle 14 ausgeübt und somit die Klappe 12 verschwenkt wird. Die Klappe 12 und der Antrieb 16 können in diesem Falle zusammen einen elektronischen Volumenstromregler bilden, mit dem der Volumenstrom einer Strömung im Strömungskanal 10 geregelt wird.Only one cuboid drive housing 18 of the drive 16 is shown here, which is arranged outside the flow channel 10. The shaft passes through an opening in the circumferential wall of the flow channel 10 and thus connects the drive 16 to the flap 12. The drive 16 can, for example, have an electronically controlled electric motor with which a torque is exerted on the shaft 14 and thus the Flap 12 is pivoted. In this case, the flap 12 and the drive 16 can together form an electronic volume flow controller, with which the volume flow of a flow in the flow channel 10 is regulated.

Die Welle 14 ist drehbar und axialfest in der Umfangswand des Strömungskanals gelagert und an der Stelle, an der sie diese Umfangswand durchsetzt, abgedichtet. Da die Welle 14 innerhalb des Antriebsgehäuses 18 mit dem hier nicht gezeigten Elektromotor oder einem zugehörigen Getriebe verbunden ist, trägt die Welle 14 zugleich zur mechanischen Befestigung des Antriebs 16 an dem Strömungskanal 10 bei. Wenn jedoch beim Schwenken der Klappe 12 um deren Achse an der Welle 14 ein gewisser Widerstand auftritt, beispielsweise durch Lagerreibung oder eine Dichtung, wenn die Klappe ihre Schließstellung erreicht, so wirkt auf den Antrieb 16 ein Reaktionsmoment, das die Tendenz hat, den gesamten Antrieb relativ zum Strömungskanal 10 um die Achse der Welle 14 zu verdrehen. Aus diesem Grund ist das Antriebsgehäuse 18 zusätzlich an einem Verdrehsicherungselement 20 gehalten, das seinerseits an der Außenwand des Strömungskanals 10 gehalten ist und so das auf das Antriebsgehäuse 18 wirkende Drehmoment in die Wand des Strömungskanals ableitet.The shaft 14 is rotatably and axially fixed in the peripheral wall of the flow channel and sealed at the point at which it passes through this peripheral wall. Since the shaft 14 is connected within the drive housing 18 to the electric motor (not shown here) or an associated gear, the shaft 14 also contributes to the mechanical attachment of the drive 16 to the flow channel 10. However, if there is a certain resistance when pivoting the flap 12 about its axis on the shaft 14, for example due to bearing friction or a seal, when the flap reaches its closed position, a reaction moment acts on the drive 16, which tends to affect the entire drive to rotate relative to the flow channel 10 about the axis of the shaft 14. For this reason, the drive housing 18 is additionally held on an anti-rotation element 20 which in turn is held on the outer wall of the flow channel 10 and thus derives the torque acting on the drive housing 18 into the wall of the flow channel.

Im gezeigten Beispiel gliedert sich das Verdrehsicherungselement 20 in einen Stützteil 22, der ein Segment des gekrümmten Außenumfangs des Strömungskanals 10 umgreift, einen Konsolenteil 24, an dem das Antriebsgehäuse 18 befestigt ist, und einen Verbindungsteil 26, der den Stützteil 22 mit dem Konsolenteil 24 verbindet. Wahlweise kann der Stützteil 22 mittels Schrauben oder Nieten an der Umfangswand des Strömungskanals 10 fixiert sein. Ebenso kann auch das Antriebsgehäuse 18 mittels Schrauben oder Steckverbindung an dem Konsolenteil 24 befestigt sein.In the example shown, the anti-rotation element 20 is divided into a support part 22 which encompasses a segment of the curved outer circumference of the flow channel 10, a console part 24 to which the drive housing 18 is fastened, and a connecting part 26 which connects the support part 22 to the console part 24 , The support part 22 can optionally be fixed to the peripheral wall of the flow channel 10 by means of screws or rivets. Likewise, the drive housing 18 can also be fastened to the console part 24 by means of screws or a plug connection.

Bei dem Verdrehsicherungselement 20 handelt es sich um eine einstückige Platte, beispielsweise aus Blech oder thermoplastischem Kunststoff, die mehrere vorgeschwächte Biegelinien aufweist. Zwei dieser Biegelinien sind in Fig. 1 gezeigt und mit A und B bezeichnet. Diese beiden Biegelinien trennen einerseits den Stützteil 22 vom Verbindungsteil 26 und andererseits den Verbindungsteil 26 vom Konsolenteil 24.The anti-rotation element 20 is a one-piece plate, for example made of sheet metal or thermoplastic, which has several pre-weakened bending lines. Two of these bend lines are in Fig. 1 shown and with A and B designated. These two bending lines separate the support part 22 from the connecting part 26 on the one hand and the connecting part 26 from the console part 24 on the other hand.

In Fig. 2 ist das Verdrehsicherungselement 20 in vergrößertem Maßstab gezeigt. Der Konsolenteil 24 wird durch zwei in einer gemeinsamen Ebene liegende Laschen 28 gebildet, die in der hier gezeigten Konfiguration längs der Biegelinie B um 90° vom Verbindungsteil 26 abgewinkelt sind. Zwischen den beiden Laschen 28 ist eine Zunge 30 gebildet, die in Verlängerung des Verbindungsteils 26 aufragt und eine sichere Positionierung des Antriebs erlaubt. Die Zunge 30 hat eine T-förmige Gestalt mit einem vertikalen Schenkel 30a und einem Querbalken 30b.In Fig. 2 the anti-rotation element 20 is shown on an enlarged scale. The console part 24 is formed by two brackets 28 lying in a common plane, which in the configuration shown here are angled by 90 ° along the bending line B from the connecting part 26. Between the two tabs 28, a tongue 30 is formed, which protrudes in the extension of the connecting part 26 and allows safe positioning of the drive. The tongue 30 has a T-shaped shape with a vertical leg 30a and a crossbar 30b.

Durch längs der Biegelinie B angeordnete Schlitze 32 wird eine Vorschwächung erreicht, so dass sich durch Biegen der Platte an der Biegelinie B die Winkelstellung der Laschen 28 relativ zum Verbindungssteil 26 auf einfache, werkzeuglose und damit sogar manuelle Weise verändern lässt.Preliminary weakening is achieved by means of slots 32 arranged along the bending line B, so that the angle position of the tabs 28 relative to the connecting part 26 can be changed in a simple, tool-free and thus manual manner by bending the plate on the bending line B.

Durch weitere Schlitze 34 wird die Platte auch längs der Biegelinie A geschwächt.The plate is also weakened along the bending line A by further slots 34.

In Fig. 2 ist weiterhin zu erkennen, dass sich die Biegelinie A nicht exakt an der Grenze zwischen dem Stützteil 22 und dem Verbindungsteil 26 befindet, sondern am oberen Ende eines Steges 36, der von dem Stützteil 22 um 90° nach oben abgekantet ist. Der Stützteil 22 gliedert sich in einen Basisteil 38, an dem sich auch der Steg 36 befindet, und zwei seitliche Laschen 40, die an weiteren Biegelinien C leicht vom Basisteil 38 abgewinkelt sind, so dass sie den Umfang des Strömungskanals 10 umgreifen und somit eine formschlüssige Verbindung zu dem Strömungskanal herstellen. Auch an den Biegelinien C ist die Platte durch Schlitze 42 geschwächt.In Fig. 2 it can also be seen that the bending line A is not exactly at the boundary between the support part 22 and the connecting part 26, but at the upper end of a web 36 which is bent upwards by 90 ° from the support part 22. The support part 22 is divided into a base part 38, on which the web 36 is also located, and two side tabs 40, which are slightly angled from the base part 38 at further bending lines C, so that they encompass the circumference of the flow channel 10 and thus form-fit Establish connection to the flow channel. The plate is also weakened by slots 42 at the bending lines C.

Fig. 3 zeigt das Verdrehsicherungselement 20 in der Konfiguration gemäß Fig. 1 und 2 in einer Seitenansicht, zusammen mit einem Teil des Antriebsgehäuses 18 und einem Teil des Strömungskanals 10. Durch den Verbindungsabschnitt 26 wird in dieser Konfiguration ein relativ großer Abstand zwischen dem Scheitel des Strömungskanals 10 und dem Boden des Antriebsgehäuses 18 hergestellt. Dies ermöglicht es, eine ggf. notwendige Isolierung direkt auf die Oberfläche des Strömungskanals zu bringen; sowohl werkseitig als auch bauseits. Die Zunge 30 durchgreift in diesem Beispiel eine Öffnung im Boden des Antriebsgehäuses 18. Fig. 3 shows the anti-rotation element 20 in the configuration according to FIG 1 and 2 in a side view, together with part of the drive housing 18 and one Part of the flow channel 10. In this configuration, the connecting section 26 creates a relatively large distance between the apex of the flow channel 10 and the bottom of the drive housing 18. This makes it possible to bring any necessary insulation directly onto the surface of the flow channel; both at the factory and on site. In this example, the tongue 30 extends through an opening in the bottom of the drive housing 18.

Fig. 4 zeigt das Verdrehsicherungselement 20 in einer anderen Konfiguration, in der der Abstand zwischen dem Strömungskanal 10 und dem Antriebsgehäuse 18 deutlich verringert ist. Das wird dadurch erreicht, dass der Verbindungsteil 26 an der Biegelinie A um 90° gegenüber dem Steg 36 umgebogen wird, während andererseits die Laschen 28 an der Biegelinie B in die Ebene des Verbindungsteils 26 zurückgebogen werden. Diese Ausführung wird insbesondere dann gewählt, wenn keine Isolierung des Strömungskanals notwendig ist oder wenn beengte Platzverhältnisse eine kompakte Anordnung von Antrieb und Strömungskanal verlangen. Fig. 4 shows the anti-rotation element 20 in another configuration, in which the distance between the flow channel 10 and the drive housing 18 is significantly reduced. This is achieved in that the connecting part 26 on the bending line A is bent 90 ° relative to the web 36, while on the other hand the tabs 28 on the bending line B are bent back into the plane of the connecting part 26. This version is chosen in particular when no insulation of the flow channel is necessary or when space is limited and a compact arrangement of the drive and flow channel is required.

Beim Umbiegen der Platte an der Biegelinie A bleibt eine aus dem Verbindungsteil 26 ausgesparte Zunge 44 stehen, die nun anstelle der in Fig. 2 gezeigten Zunge 30 zur Positionierung und Fixierung des Antriebsgehäuses 18 dient.When the plate is bent at the bending line A, a tongue 44 which has been left out of the connecting part 26 remains and which is now in place of the one in FIG Fig. 2 tongue 30 shown for positioning and fixing the drive housing 18 is used.

Fig. 5 zeigt das Verdrehsicherungselement 20 in der Konfiguration gemäß Fig. 4 in einer Stirnansicht, zusammen mit einem Teil des Querschnittes des Strömungskanals 10. Fig. 5 shows the anti-rotation element 20 in the configuration according to FIG Fig. 4 in an end view, together with part of the cross section of the flow channel 10.

Fig. 6 zeigt eine Stirnansicht des Verdrehsicherungselements 20 in einer Konfiguration, in der die Laschen 40 an den Biegelinien C weiter aufgebogen sind, so dass der Basisteil an einen Strömungskanal 10' mit größerem Durchmesser angepasst ist. Fig. 6 shows an end view of the anti-rotation element 20 in a configuration in which the tabs 40 are further bent at the bending lines C, so that the base part is adapted to a flow channel 10 'with a larger diameter.

Fig. 7 zeigt eine Installation gemäß einem anderen Ausführungsbeispiel in der Draufsicht. Für die Befestigung des Antriebsgehäuses ist hier auf den Laschen 28 des Verdrehsicherungselements 20 eine zusätzliche Konsolenplatte 46 befestigt, in der die Welle 14 drehbar gelagert ist und auf der das hier nicht gezeigte Antriebsgehäuse montiert werden kann. Die Konsolenplatte 46 weist ein Langloch 48 auf, das von der Zunge 30 (oder wahlweise 44) so durchgriffen wird, dass der vertikale Schenkel 30a passend in das Langloch eingreift und so die Konsolenplatte 46 gegen Verdrehung um die Welle 14 sichert, während der Querbalken 30b den Rand des Langloches übergreift und die Konsolenplatte gegen ein Abheben nach oben sichert. Auch in diesem Ausführungsbeispiel kann die Zunge 30 (oder wahlweise 44) noch dazu verwendet werden, einen Antrieb zu positionieren und zu fixieren. Bei der Montage kann das Verdrehsicherungselement in einer leichten Drehbewegung so eingesetzt werden, dass der Querbalken 30b durch das Langloch 48 hindurchtritt. Alternativ ist das Langloch 48 breiter als der Querbalken 30b und das Verdrehsicherungselement 20 und die Konsolenplatte 46 werden beispielsweise mittels Nieten verbunden. Fig. 7 shows an installation according to another embodiment in plan view. For fastening the drive housing is here on the tabs 28 of the anti-rotation element 20 an additional console plate 46 is attached, in which the shaft 14 is rotatably mounted and on which the drive housing, not shown here, can be mounted. The console plate 46 has an elongated hole 48, which is penetrated by the tongue 30 (or optionally 44) such that the vertical leg 30a fits into the elongated hole and thus secures the console plate 46 against rotation about the shaft 14, while the crossbar 30b engages over the edge of the elongated hole and secures the console plate against lifting upwards. In this exemplary embodiment too, the tongue 30 (or optionally 44) can also be used to position and fix a drive. During assembly, the anti-rotation element can be used in a slight rotational movement such that the crossbeam 30b passes through the elongated hole 48. Alternatively, the elongated hole 48 is wider than the crossbeam 30b and the anti-rotation element 20 and the console plate 46 are connected, for example, by means of rivets.

Im gezeigten Beispiel weist die Konsolenplatte 46 einen rechteckigen Durchbruch 50 auf, an dessen Enden zwei weitere T-förmige Zungen 52 gebildet sind, die sich aus der Ebene der Konsolenplatte heraus biegen lassen und beispielsweise dazu dienen können, Antriebe anderer Bauart, insbesondere solche mit einem größeren Gehäuse, sicher auf der Konsolenplatte zu befestigen. Auf diese Weise wird eine einfache Adaptierung an unterschiedlich gestaltete Antriebssysteme ermöglicht.In the example shown, the console plate 46 has a rectangular opening 50, at the ends of which two further T-shaped tongues 52 are formed, which can be bent out of the plane of the console plate and can be used, for example, for drives of a different type, in particular those with a larger housing, securely attached to the console plate. In this way, simple adaptation to differently designed drive systems is made possible.

In einer modifizierten Ausführungsform können die Zungen 30 und/oder 44 anders konfiguriert oder angeordnet sein, um eine Anpassung an unterschiedlich gestaltete Antriebsgehäuse zu ermöglichen. Beispielsweise können die Zungen auch Rastnasen für eine Rastbefestigung des Antriebsgehäuses oder anderer Komponenten aufweisen.In a modified embodiment, the tongues 30 and / or 44 can be configured or arranged differently in order to enable adaptation to differently designed drive housings. For example, the tongues can also have latching lugs for latching the drive housing or other components.
